Topoisomerase I Inhibitors

Compounds that inhibit the activity of DNA TOPOISOMERASE I.
DrugDrug NameDrug Indication
DB00762IrinotecanFor the treatment of metastatic colorectal cancer (first-line therapy when administered with 5-fluorouracil and leucovorin). Also used in combination with cisplatin for the treatment of extensive small cell lung cancer. Irinotecan is currently under investigation for the treatment of metastatic or recurrent cervical cancer. Also used in combination with fluorouracil and leucovorin for the treatment of patients with metastatic adenocarcinoma of the pancreas after disease progression following gemcitabine-based therapy.
DB01030TopotecanFor the treatment of advanced ovarian cancer in patients with disease that has recurred or progressed following therapy with platinum-based regimens. Also used as a second-line therapy for treatment-sensitive small cell lung cancer, as well as in combination with cisplatin for the treatment of stage IV-B, recurrent, or persistent cervical cancer not amenable to curative treatment with surgery and/or radiation therapy.
DB04690CamptothecinInvestigated for the treatment of cancer.
DB06159RubitecanInvestigated for use/treatment in pancreatic cancer, leukemia (unspecified), melanoma, ovarian cancer, and cancer/tumors (unspecified).
